Joris Van den Bossche updated ARROW-10284:
------------------------------------------
    Description: 
This happens on import (when setting the warning to be visisble), so even when 
the user doesn't use the deprecated filesystems:

{code}
In [1]: import warnings

In [2]: warnings.simplefilter("always")

In [3]: import pyarrow
/home/joris/scipy/repos/arrow/python/pyarrow/filesystem.py:255: 
DeprecationWarning: pyarrow.filesystem.LocalFileSystem is deprecated as of 
2.0.0, please use pyarrow.fs.LocalFileSystem instead.
  cls._instance = LocalFileSystem()
{code}

I forgot to add a filter in the construction of the LocalFileSystem ..
